A pseudojoint estimation of time scale and time delay between an unknown deterministic transient type signal and a reference signal is proposed. The method is based on the separation between the estimations of the two dependent parameters. The time autocorrelation function (TACF) preserves the time scale and is invariant with respect to the time delay(More)
In this paper, a new method for the estimation of the direction-of-arrival (DOA) and relative propagation delay in the context of multipath rays is described. The proposed algorithm processes the received signals at a uniform circular array and uses ESPRIT-like approach for the estimation of the relevant parameters. We show, in particular that in the(More)
A performance comparison between radio location positioning (LP) in Wide band Code Division Multiple Access (WCDMA), more precisely in UMTS FDD cellular phones, using the Uplink (UL) and Downlink (DL) scenarios, is carried out. The radio location algorithm using the Time Difference Of Arrival (TDOA) is applied, where the TDOA is the difference between two(More)
